Hello Aaron, apologies for not getting back to you sooner. First of all, welcome to the Baserow community 
Baserow is an open source project, funded using an open-core business model. The majority of our time, we spend on developing free, open source features. But we also work on the Premium offering, as this model funds our team and ensures we release new free features quickly. We are not hiding it and we clearly communicate which features are available in which version. We can also openly give a promise that any feature present in the free open source Baserow project will always remain free and fully open source.
We understand and respect your position as being FLO activist and advocate. Besides, we are also fighting against the vendor lock-in problem with Baserow. We believe open source is extremely valuable for business continuity independent, and we want our users never to be faced with the risk of our company disappearing, being acquired, or changing the pricing strategy.
The premium Baserow plugin’s source code is available for everyone to view and vet in the same repository as our main code-base. Our main code-base is all licensed under the MIT License which allows you to modify and build on top of Baserow. And we always welcome our community for open participation in product development trying to build honest and transparent relationships with our active members.
